Power Up and Power Down Sequencing
MRAM is protected from write operations whenever V

ory power supplies to stabilize.
The E and W control signals should track V
remain high for the startup time. In most systems, this means that these signals should be pulled up with
a resistor so that signal remains high if the driving signal is Hi-Z during power up. Any logic that drives E
and W should hold the signals high with a power-on reset signal for longer than the startup time.
During power loss or brownout where V
